Alexander Markov 80f12af7e8 [frontend_server] Add --no-print-incremental-dependencies option to suppress extra frontend_server output
Front-end server prints all dependencies after compilation, which could
result in a lot of output when AOT compiling a large application.

This change adds --no-print-incremental-dependencies option which
suppresses extra output. This skips printing dependencies which
takes time and avoids I/O which may be blocked.

Anna Gringauze 34052bf2bb Add expression evaluation to ddc for google3
- Move expression evaluation to ddc in preparation for google3
- Added server to ddc to handle update and compileExpression requests
- Added tests
- Added 'experimental-output-compiled-kernel' option to ddc to generate
  full kernel files only for compiled libraries, and store with
  '.full.dill' extension
- Added AssetFileSystem to communicate to the asset server in the
  debugger
- Made expression_compiler_worker work with full kernel files,
  so removed invalidation of current file to improve performance
- Made expression_compiler_worker reuse already loaded imports
  to avoid reading them from source in the incremental compiler
- Updated tests to work with DDC (for simulating webdev)
- Disabled tests that work with bazel kernel worker for now
  as it does not generate full dill files yet
- Addressed code review comments from the prototype version:
  https://dart-review.googlesource.com/c/sdk/+/157005

Details:

Currently, in flutter tools, expression evaluation is supported via
expression compilation, which is done by the incremental compiler in
the frontend server. The same incremental compiler is used for initial
application compilation, incremental code compilation for hot reload,
and any number of expression compilation requests.

In google3, the apps are typically too large to be compiled as a whole
in memory by the frontend server. Build in google3 is currently done by
blaze, as a distributed build using a task dependency graph. Build tasks
output kernel outline files as an interface between components produced
by individual tasks.

We are proposing an implementation of the expression compilation in
google3 that is taking advantage of full kernel files produced by the
build (supporting build changes to follow). This change introduces a
small server based on dev_compiler, which can handle following requests:

- update: load full kernel for given modules (done on app start)
- compileExpression: compile expression in a given library and module
  (done when paused on a breakpoint)

Expression compilation uses previously loaded kernel files for the
application component and its dependencies to compile an expression.

Alexander Markov 467c98b846 [vm/aot/tfa] Re-implement protobuf-aware tree shaker inside TFA
This change introduces handling of protobufs while doing type flow
analysis. Metadata in protobuf message classes is updated dynamically
according to the set of called accessors, invalidating and rebuilding
TFA summaries as needed.

Previously, protobuf-aware tree shaker required the 2nd run of TFA
in order to do the actual tree-shaking after protobuf messages are
pruned. This significantly increases compilation time.

AOT compilation time of a large app (--from-dill): 274s -> 152s

New tree shaker is available in kernel compilers under the flag
--protobuf-tree-shaker-v2.

Alexander Markov ecc7a21106 [vm/kernel] Add --from-dill option to kernel compilers
This option can be used to split AOT kernel generation into two rounds:

* The 1st round uses CFE to parse source files and generate intermediate
  dill file in *non-AOT* mode.

* The 2nd round loads intermediate dill file and applies AOT global
  transformations, then generates final dill file.

Each round is faster than one-shot generation of a dill file in AOT mode.

In order to use this 2-round compilation, command

  gen_kernel <other-options> --aot -o output.dill main.dart

should be replaced with the following 2 commands:

  gen_kernel <other-options> --no-aot -o intermediate.dill main.dart
  gen_kernel <other-options> --aot --from-dill intermediate.dill -o output.dill main.dart

Jens Johansen 86f3fde23f [frontend_server] Plug leaks caused by saving the first compilation result
The first compilation result is leaked in two ways:
1) Directly by saving the component in a variable; and
2) Via an unfortunate context thing, probably a variation of
   http://dartbug.com/36983. I will update that bug with a reproduction
  example later.

The reason this creates a (big) leak is illustrated with an example:
* Say the first component (A) has 10 libraries in it. Each of these
  libraries has parent pointers and points (currently) to A, which again
  points to all of the 10 libraries.
* We then do a recompilation, say 5 libraries are reused and 5 are new.
  They are put into a component (B). We really should have 10 libraries,
  the 5 old ones and the 5 new ones (and for simplicity lets say these are
  the ones in B). Notice that the 5 old ones will have their parent
  pointers updated and also still be in the list of libraries in A.
  We keep 15 libraries alive because we have the 10 original ones saved via
  A and the 10 (where 5 is new) saved via B.
* We then do a recompilation, say 2 of the same libraries as was also
  recompiled before, these end up in compnent C which has 5 libraries from A,
  3 libraries from B and the 2 new ones. All of these libraries will have
  their parent pointers updated to point to C.
* Because we saved A we keep all the 10 libraries in A though.
  Because we saved A and some of the libraries in A had parent pointers
  updated to point to B we also keep B and all libraries in B.
  Because we keep B and some of the libraries in B had parent pointers
  updated to point to C we also keep C and all libraries in C.
  So instead of only having the 10 "live" libraries, we have 10 + 5 + 2 = 17
  libraries, a leak of 7. With more compilations this keeps happening and
  the leak keeps growing.

This CL stops the leak by not holding on to A (which, in turn, stops holding
on to B etc.)

a type that was not used in the current function, the incremental

function.

Alexander Markov d1b9a93363 Revert "[vm/nnbd] Auto-detect null-safety from entry point in kernel compilers"
This reverts commit fd19c8cc25.

Reason for revert: Flutter has tests with --enable-experiment=non-nullable, but dart:ui is not migrated yet and gen_snapshot doesn't detect null-safety from kernel file. This change causes failures in those tests as dill file is now compiled with null-safety enabled due to the auto-detection.

Original change's description:

Anna Gringauze 6f16174d56 remove private fields and modules calculations from expression compiler
- Remove collecting private fields from scope calculation
  We only need to collect the fields from the evaluated
  expression and they are already collected separately.

- Correct private fields calculation
  Currently, library names are assumed to be the same as the module,
  which creates redefinitions of library variable in produced Javascript
  code, and exceptions in chrome for modules that contain more than one
  library.
  The actual fix will come from making DDC incremental by storing more
  information, for now make a best effort to compute correct names for
  library variables from the module data that expression compiler
  receives from chrome. The following code will be produced to calculate
  private symbols _pf1 (from lib1, module1) and _pf2
  (from lib2 module1):

  let lib1 = require('module1.dart').lib1;
  let lib2 = require('module1.dart').lib2;

  let _pf1 = dart.privateNames(lib1, '_pf1');
  let _pf2 = dart.privateNames(lib2, '_pf2');

  Note that this seems to work even if the current breakpoint is inside
  the define statement for lib1, and the lib1 symbol is not exported
  yet.

Robert Nystrom d9bb487ca8 Treat the expect and async_helper packages as opted in to NNBD.
This should enable strong mode tests to be fully NNBD opted in. At the
same time, legacy tests when run with the experiment off should
hopefully be able to still consume these libraries because they don't
actually use any NNBD features.

To do this, I changed the script that generates the SDK repo's package
config to not put in a language version for any package whose pubspec
has no SDK version. According to language versioning, that means the
package should be considered to be at the "current" version of the SDK
running the code.

In NNBD, that's opted in. With the experiment off, that is (presumably)
"opted out" in the sense that NNBD doesn't exist.

In order to *not* opt in some of the other packages that currently
lack SDK constraints, I put those in and pinned them to "^2.7.0" which
was what the package config script used to implicitly fill in for them.

I see a bunch of other changes in the generated package config too. The
update script probably hasn't been run in a while.

Anna Gringauze bd3d08a891 Convert exceptions on expression evaluation to errors
Currently expression evaluation in frontend server throws exception
when it cannot find a ProgramCompiler (DDC) to compile the module
where the expression is located. Given that IDEs use expression
evaluation for many information displaying cases, such as watch window,
hover over, and more, this results in unexplained exceptions thrown
during debugging.

Instead of throwing exception, return an error for the debugger
to report.

Alexander Markov 12c8b02c84 Reland "[vm/aot/tfa] Tree shake write-only fields"
This relands commit ff34fd8110,
but puts tree shaking of write-only fields under the flag which is
disabled by default.

So far tree shaking was removing fields which are not used at all.
This change improves tree shaking of fields so fields
which are only written or used as interface targets can be removed.

The following limitations apply:

* Field is not removed if there is a constant object with that field, as
  it may impact identity of constant objects which is an observable
  behavior.
* Instance field is not removed if it has a non-trivial initializer as
  it may have side-effects when executed by constructors.
* Late final fields are not removed, as writing such fields may have
  side-effect.
* When field is removed, we may need to introduce an abstract getter
  or abstract setter if field is used as a target of an interface call.
  If a field was written, then setter would be non-abstract (but empty).

Anna Gringauze 9f65693f57 Use offset for detecting scope in ExpressionCompiler
ExpressionCompiler currently translates offsets of scopes to line
numbers during the binary search in the library in order to find
the inner-most scope containing the line where debugger has stopped.
This results in many offset-to-line translations per evaluation request,
each translation also performing a binary search in Source.lineStarts
table.

To make scope lookup more efficient, this change uses Source.lineStarts
table to find the offset for the debugger stop once, and uses integer
offset comparisons instead in the scope binary search.

Anna Gringauze 7466c1f9da [frontend_server] Make module names debugger-friendly
Module names and import module names generated by the frontend server
are currently breaking debugger's assumptions on module names. This
change fixes it to make debugger works with various compiler
configurations, such as build_runner, frontend server with dwds tests,
and unblocks flutter tools to continue debugger and frontend server
integration.

JavaScriptBundle
  - Change module import names to module names instead of file paths,
    omit leading '/' as it cannot be in a module name in requireJS
  - Module name changes are hidden under "debugger-module-names" flag
    to prevent breaking flutter tools.

FrontendServer
  - Always call exit after listening to commands is finished,
    otherwise process running frontend server does not exit on 'quit'
    command.
  - Call computeCanonicalNames after initial compilation to support
    subsequent module importing in compileExpressioToJs calls
  - Add error handling to usage of kernelToJs compilers

ExpressionCompiler
  - Separate library variables from library fields for loading modules,
    as they can be different, for example
    ```main = require('web/main.dart').web__main```

Jacob MacDonald d3070f4bbc - simplify convertFileOrArgumentToUri to just use resolveInputUri
- Allow non-file uris as a multi-root root

resolveInputUri already does what we need, and also supports other types of uris such as http.

This enables us to set a multi-root uri which is actually pointing to a dev server, thus hiding the server uri from generated kernel files.

Also updates StrongComponents to prefer the main component as the root if it is in a cycle. This makes bootstrapping more predictable.

This enables a clean integration of build_runner or ddr (internal) and the frontend_server by allowing it to work with any dev server.

All that is needed is a custom .packages file with `http` uris pointing at a dev server which does all code generation, etc.

Nate Bosch 113ff6c993 Enforce that allowInterop is used in DDC
Fixes #39074

DDC emits Dart code that can usually be called with the same semantics
as JS there is no guarantee that a function passed to JS and then
invoked successfully was wrapped with `allowInterop`. The wrapping is
always required in Dart2JS. To make DDC more strict, add interceptors
that check for the usage of `allowInterop`.

Whenever a JS interop function or setter is passed an argument which is
statically typed as a Function, but not wrapped with `allowInterop` at
the call site, wrap it with `assertInterop` which will check the
argument at call time and fail with a clear error if it was not wrapped.

Whenever a JS interop function is torn off, either at the top level or
from an instance, wrap it with a function that will also inject these
checks at runtime.

There are still holes where we can't catch the mistake:
- An argument which is statically dynamic and a Function at runtime
  won't be caught.
- A Function which is stored in a collection won't be caught.
- A JS interop definition where a getter returns a Function which takes
  a Function as an argument is not checked.
- A dynamic call through to javascript is not checked.

Changes:

- Refactor `_isJsLibrary` and add `isJsMember`, and `isAllowInterop`
  utilities to determine what needs wrapping.
- Update `assertInterop` to give a more clear error when it fails, and
  to ignore non function arguments.
- Add `tearoffInterop` to wrap a function an ensure that any function
  typed arguments are wrapped.
- Inject `assertInterop` around Function arguments passed to JS methods.
- Inject `assertInterop` around Function arguments passed to static or
  instance JS setters.
- Inject a runtime wrapper around static or instance Function tearoffs.
- Add a test covering all flavors of checks that are supported.
- Change the interop expando to an `Expando<dynamic>` in the NNBD SDK to work
  around a stricter type check. https://github.com/dart-lang/sdk/issues/39971

Potential improvements:

If the `tearoffInterop` turns out to be too heavy, we could loosen it so
that we only wrap methods if any of their argument types are statically
declared to be a Function.

Original change was broken by the fact that DDC expects all types marked as
native have all their superclasses marked as native when the super classes are
compiled.

In this case `MapMixin` from dart:collection was not being marked as native and
the only reason it was working before was that the library dependency enforced
the necessary order.

* Now `MapMixin` is explicitly marked as native.
* Added a test case to use some of the API on `window.localStorage` that is
  inherited from the MapMixin class.

Alexander Markov 86641d07ae [vm, front-end server] Cache generated bytecode using separate file
Previously, generated bytecode was cached using metadata in kernel AST.
When serializaing kernel AST (for subsequent compilations) incremental
serialization was not used, so AST serialization was considerably
slower in bytecode mode compared to non-bytecode mode.

Apparently, metadata is not compatible with incremental serialization
(https://github.com/dart-lang/sdk/issues/39302).

This change reimplements caching of generated bytecode using a separate
'foo.dill.cache' file near the generated 'foo.dill' and 'foo.dill.ast'.
AST is now written using incremental serialization both in bytecode
and non-bytecode modes.

  "implementation_change_elapsed_time_ms": 6292-6394,

jonahwilliams c26d5969f7 [flutter] JavaScript support to frontend_server
Adds support to the frontend server for producing javascript when
compiling with a target model of dartdevc. This uses the ProgramCompiler
and associated types from the dev_compiler package to output the kernel
AST into a "bundle" format.

dev_compiler:
* Exposes additional types needed for JavaScript compilation.
* Allows  overriding CoreTypes instead of forcing it to be created from
Component. This is require to support compilation of the
partial Components created by the incremental compiler.
* provides extraIndexedLibraries in Target class so the CoreTypes produced by the incremental compiler have indexed them.

frontend_server:
* When the target model is dartdev, JavaScript is output instead of
kernel. For each Component we compile, we first compute the strongly
connected components and produce a List of new Components to interop
with the dev compiler. The file uri is used as module name.

$ flutter test --local-engine=host_debug
[...]
01:32 +5149 ~27: All tests passed!

[...]
08:33 +5149 ~27: All tests passed!

$ flutter test --local-engine=host_debug --coverage
[...]
08:34 +5149 ~27: All tests passed!


So, without coverage more than twice as fast!
With coverage ~no change (which makes sense considering it's the VM thats spending extra time collecting coverage, so the compilation is not the bottleneck).


Running "flutter test" in a new project created with "flutter create" (i.e. with a single test):


BEFORE ENABLING
===============
$ time flutter test --local-engine=host_debug
00:05 +1: All tests passed!

real    0m6.360s
user    0m8.783s
sys     0m0.987s

$ time flutter test --local-engine=host_debug
00:02 +1: All tests passed!

real    0m2.790s
user    0m3.089s
sys     0m0.962s

$ time flutter test --local-engine=host_debug
00:02 +1: All tests passed!

real    0m2.693s
user    0m2.872s
sys     0m0.933s

WITH THIS ENABLED
=================
$ time flutter test --local-engine=host_debug
00:05 +1: All tests passed!

real    0m6.356s
user    0m8.253s
sys     0m1.161s

$ time flutter test --local-engine=host_debug
00:02 +1: All tests passed!

real    0m3.035s
user    0m3.449s
sys     0m0.880s

$ time flutter test --local-engine=host_debug
00:02 +1: All tests passed!

real    0m3.055s
user    0m3.534s
sys     0m0.885s

So maybe ~10% improvement on non-first runs (where it reuses the serialization from the dill it initialized from).
~no change on a clean run.
